"docker pull" 使用 Gitlab Runner 部署到 Digital Ocean 时 requires exactly 1 argument 错误

Question

晚上好，我正在尝试部署我的 nodejs 应用程序并使用 pm2 使其运行并使用 Docker，但 Docker 抛出“”docker pull” 正好需要 1 个参数。参见 'docker pull --help'。用法：docker pull [OPTIONS] NAME[:TAG|@DIGEST] 从注册表中拉取图像或存储库”错误。感谢您的帮助，感谢您的宝贵时间。

  ## Use ssh-keyscan to scan the keys of your private server. Replace gitlab.com

  ## Alternatively, assuming you created the SSH_SERVER_HOSTKEYS variable

错误信息：

"docker pull" requires exactly 1 argument

表示行：

ssh  -o StrictHostKeyChecking=no $SERVER_USER@$SERVER_IP 'docker pull $TAG_COMMIT'

不正确。

要么 $TAG_COMMIT 为空（因此没有参数传递给 docker pull）
或 $TAG_COMMIT 中有一个 space（使其两个参数传递给 docker pull
或 $TAG_COMMIT 未被其值替换并在 ssh 'docker pull $TAG_COMMIT' 会话中保持为空。
使用双引号会有所帮助 (ssh "docker pull $TAG_COMMIT")，确保 shell 在发送到远程 shell 之前可以解释 $TAG_COMMIT 。

我会仔细检查（回显）以下值：

TAG_COMMIT: $CI_REGISTRY_IMAGE/$CI_COMMIT_REF_NAME:$CI_COMMIT_SHORT_SHA

该变量的每个分量（$CI_REGISTRY_IMAGE、...）

这样，我就能明白为什么传递给 docker pull 的参数不正确了。
